Replication marketplaces would help science to become more self-correcting.

Independent replications are very rare in the behavioural and social sciences. This is problematic because they can help to detect 'false positives' in published research and, in turn, contribute to scientific self-correction. The lack of replication studies is, among other factors, due to a rather passive editorial approach concerning replications by many journals, which does not encourage and may sometimes even actively discourage submission of replications. In this Perspective article, we advocate for a more proactive editorial approach concerning replications and suggest introducing journal-based replication marketplaces as a new publication track. We argue that such replication marketplaces could solve the long-standing problem of lacking independent replications. To establish these marketplaces, a designated part of a journal's editorial board identifies the most relevant new findings reported within the journal's pages and publicly offers them for replication. This public offering could be combined with small grants for authors to support these replications. Authors then compete for the first accepted registered report to conduct the related replications and can thus be sure that their replication will be published independent of the later findings. Replication marketplaces would not only increase the prevalence of independent replications but also help science to become more self-correcting.
